FIREPROOF GRAIN-BIN, ELEVATOR, 800i SPECIFICATION forming part of Letters Patent No. 664,325, dated December 18, 19cc.

Application filed J ne 4. 1900. Serial No. 18,978. (No model.)

To all whom it maly conoern:

Be it known that I, ERNEST V. JOHNSON, a citizen of the United States, residing in Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Fireproof Grain Bins, Elevators, or other Buildings, of which the following is a specification.

My invention relates to improvements in the construction of fireproof grain-bins, elevators, or other buildings, the walls of which are subjected to great outward or bulging pressure, as well as to great weight or crushing force from the grain or other material confined within and by its walls, and which are necessarily of large capacity and great height.

The object of my invention is to provide a simple, cheap, strong, durable, practical, and efficient construction of fireproof building for containing grain or other material of great weight, which when stored to great height tends to exert great outward or bulging pressure on the structure, and which fireproof construction shall at the same time be such as to enable it to be rapidly and cheaply erected.

My invention consists in the means I employ to practically accomplish this result that is to say, it consists in a fireproof cylindrical building or grain bin having cylindrical masonry walls composed of horizontal courses of hollow tile arranged with the webs and hollows of the tile upright and courses of trough-shaped tile arranged with the Webs and troughs of the tile horizontal and forming continuous annular channels around the circular wall at intervalsin the height of the wall, and tensile acting metal members or bands arranged in the annular troughs or channels formed by the courses of troughshaped tile, said tensile acting metal members or bands being united throughout their length and width with the tilework wall by cement, which fills such annular troughs or channels and in which the metal bands are embedded. The tensile acting members or metal bands are thus anchored at every point of their length in the cement and to the wall, and thus aiford great tensile strength to the weight or amount of metal employed. The tensile members thus give great strength and support to the wall against outward or bulging pressure without adding materially to its cost, and as the horizontally-arranged troughshaped tile form an open channel to receive the metal bands and the cement the wall can be constructed very rapidly and cheaply andthe workmen are enabled to see that the tensile acting metal members or bands areproperly embedded in the cement or grouting throughout-their whole length and surface.

In the accompanying drawings, forming a part of this specification, and in which similar letters of reference indicate like parts in the several figures, Figure l is a side elevation of a grain-bin, elevator, or other building embodying my invention. Fig. 2 is an enlarged vertical section. Fig. 3is an enlarged detail plan View of one of the vertically-arranged tile. Fig. 4: is a detail perspective View of one of the trough-shaped tile. Fig. 5 is a detail perspective View showing a portion of the wall in different stages to illustrate the construction, and Fig. 6 is a plan view showing the metal members or hands, the thickness of the bands, however, being much exaggerated.

In the drawings, A represents a fireproof cylindrical grain-bin or other building, preferably from twenty to fifty feet in diameter and from fifty to one hundred feet in height, and having its fireproof tilework cylindrical wall composed in part of courses B of hollow tile 19 each ,tile 1) having preferably four open spaces b, and being equal in width-to the thickness of the wall, the webs b of the tile extending upright or in the direction of the crushing strain to give strength to the Wall against crushing force and com posed in part of coursesD of horizontally-arranged troughshaped tile d, the troughs or hollows d of which extend horizontally and circumferentially of the wall, thus forming a continuous annular channel to receive the tensile acting members F F, preferably consisting of steel bands placed edgewise and parallel to each other in such annular channel, the same being embedded throughout their entire length and surface in the cement or grouting O, which fills the annular channel formed in and by the trough-shaped tile.

In the grain-elevator bin embodying my in vention which I am now building the cylindrical wall is forty-six feet in diameter,

eighty-five feet in height, and the verticallyarran'ged tile (1 are each one foot in length, one foot in height, and six inches in width, and the horizontally-arranged trough-shaped tile are twelve inches long,six inches in Width, and three and one-half inches in thickness or height, and the tensile acting metal members are made two inches in width, five-sixteenths inch in thickness, and of any convenient length, the metal strips being lapped at their meeting ends, preferably for a distance of about four feet, and I employ three such bands in each trough or annular channel, as indicated in Fig. 2. To -give a smooth surface to the cylindrical wall on the inside thereof, I line the same with furring-tile G, the same being laid in courses to breakjoints and to form continuous air passages or flues from the bottom to the top of the wall. These continuous flues g aid in the preservation of the grain contained within the cylindrical wall and resting against the same. To provide the wall with uninterrupted continuous flues and to cause the furring-tile to contribute properly to the strength of the wall against downward or crushing strain, I provide each of the furring-tile G with outer webs g g and with double intermediate webs g 9', so that the furring-tile may be laid on top of each other in alternate courses, breaking joints with each other, while at the same time each of the outer websg will be directly in line with one of the intermediate webs g, as will be readily understood from Fig. 5 of the drawings. 7 a

While I prefer to employ for the tensile acting metal members a series of steel strips or bands placed edgewise in the annular channels formed by the trough-shaped tile, it will be understood by those skilled in the art that the tensile acting metal members may be composed of a greater or less number of such bands or strips and that the strips may be of other shapes in cross-section than that illustrated in the drawings, care, however, being taken, whatever the shape or number of the metal pieces employed, that their shape and number be such as to give a sufficient surface in the aggregate to cause the proper-anchorage thereof in the cement and that their shape be such as .to permit the cement or grouting to readily flow or be pressed down through and around the same into the channel formed by the trough-shaped tile. A series of steel wires might be used; but I prefer to employ steel strips of about the crosssection illustrated in the drawings.

0 indicates the cement or mortar forming the joints.

I claim- 1. A fireproof cylindrical grain-bin or other building having its cylindrical wall composed of courses of vertically-arranged hollow tile, and courses of trough-shaped tile forming ann ular channels, tensile acting metal members in the channels formed by said trough-shaped tile, and cement filling such annular channels and in which the tensile acting metal members are embedded throughout their length, substantially as specified.

2. A fireproof grain-bin or other building having cylindrical tilework walls, composed of courses of vertically-arranged hollow tile, and 'courses of horizontally-arranged troughshaped tile forming continuous ann ular channels at intervals around the cylindrical wall, tensile acting metal members in said channels, cement filling said channels, and furring-tile lining said wall on the inside and forming continuous vertical flues or air-passages, each of said furring-tile having outer webs g g and double intermediate webs g g .to cause the furring-tile to properly support each other and-at the same time break joints, substantially as specified.

ERNEST V. JOHNSON.
